I'd really like to avoid getting into the business of doing OS update-specific fixes to work around what seem to be semi-frequent changes to the muxing driver.
#GFXCARDSTATUS EXTERNAL DISPLAY DRIVER#
Unless you're using Integrated Only mode for the purpose of keeping your machine alive until you can get it replaced or fixed, I'd really recommend against using it at all.Īdditionally, given that this didn't seem to occur on older versions of OS X, but now does, that would seem to indicate that something about the GPU muxing driver has changed, which could be difficult to work around. As OS X has evolved, and app developers have become more aware of the perils of developing for dual GPU MacBook Pros, using Integrated Only mode has become less and less necessary.

on an incompatible machine the software has no effect but it does allow for install and be ready to run when booting a compatible machine).For quite a while, I've been suggesting that gfxCardStatus be used exclusively in Dynamic Switching to obtain information about which apps, if any, are causing your discrete GPU to turn on unexpectedly. (iii) Allow for install on another computer even if that other computer is not a compatible machine (i.e.
(ii) Allow for install in “target disk mode on another machine Allow or install on in single-user mode (that works) How can I install gfxCardStatus when I cannot get the machine to boot?
#GFXCARDSTATUS EXTERNAL DISPLAY MANUAL#
I had previously found this online: where a manual procedur is posted. Is gfxCardStatus indeed a possible solution by forcing the use of “integrated only” early enough in the process to allow boot to complete? I have the following questions for the author (and thank you for developing this software in the first place). Reading this post, the issue seems to be the same as the one reported by ttrtilley (and others). It would be great if we could use gfxCardStatus to always force the usage of the internal GPU.Ī genius bar rep suggested gfxCardStatus because my video card is bad and the system crashes before it completes the boot. Note: if I let the ATI* and AMD* extensions in place, my MBP freezes during the boot sequence Automatically updates when the GPU switches, in real time. Features: Simple, clean 'i' and 'n' icons that signify Intel HD Graphics, and NVIDIA GeForce GT 330M graphics, respectively. Today gfxCardStatus is used by a lot of the owners of early 2011 MBPs who have troubles with the external Radeon GPU.įor example, to be able to boot my MBP 8.2, I must remove the ATI* and AMD* extensions, but in this case, the selected GPU is the Radeon GPU and gfxCardStatus is not able to force the usage of the integrated GPU because it detects an external display even I have no plugged external display !. gfxCardStatus is a free menu bar application that keeps track of which graphics card your MacBook Pro is using at any given time. Ogattaz gives an excellent description of this problem in: This problem also occurs when booted "Safe Mode". This may allow your MBP to run normally, although it will have reduced graphics performance when permforming demanding graphics tasks. kext files to get it to boot all the way to login screen. Install gfxCardStatus ( and set it to 'i' (integrated graphics only).It will allow your MBP to run on integrated graphics only, bypassing the discrete GPU which has the issues. Strangely enough, it DOES allow "Discrete Only" and also allows Dynamic.
